Ososayensi badale ipulasitiki elilingana nensimbi - eliqinile kodwa alindile.prastics, amakhemikhali angenawo ama-polymecune afanayo abizwa nge-polymer.Izwi eliphakeme kakhulu kune-polymer. Inqubo, eyenzeka emazingeni okushisa asekamelweni, idinga kuphela izinto ezishibhile, futhi i-polymer ingakhiqizwa ngamashidi amakhulu ama-nanometer kuphela ama-nanometers aminyene.I-2 ebika okutholakele ngoFebhuwari 2.
Izinto ezishiwo kumbuzo zibizwa nge-polyamide, inethiwekhi enomugqa wamayunithi we-molefanelar (ama-antides amaqembu amakhemikhali we-nitrogen anamathele kuma-athomu ama-ovelgen carbon) Amabhondi e-Hydrogen kanye nobude obude bamaketanga abo, athuthukisa amandla aphelele ento ethile.
"Banamathela ndawonye njenge-velcro," kusho umlobi we-lead uMichael Strano, izinto zokuzilungiselela ze-MIT Chemical mpashini azidingi ukuphula amaketanga ama-hydrogen ama-hymeate kuphela, kodwa futhi anqobe ama-hymolecular ama-hydrogen ama-hydrogen avela sonke isigaxa se-polymecula.
Ngaphezu kwalokho, ama-polymers amasha angakha ama-flakes.Lokhu enza okulula ukucubungula, ngoba angenziwa abe amafilimu ancanyana noma axhumene nama-polymers akhule, kungakhathalekile ukuthi ama-polymers angenamikhawulo akhula ngendlela eyingqayizivele.
"Ungahlanganisa ephepheni? Kuyavela, ezimweni eziningi, awukwazi ukukwenza kuze kube ngumsebenzi wethu," kusho uStrano. "Ngakho-ke, sathola indlela entsha." Kulomsebenzi wakamuva, iqembu lakhe lahlula inkinga ukwenza lokhu kuhlangana okunezinhlangothi ezimbili.
Isizathu se-polyaramides sinesakhiwo seplanethi ukuthi ukuhlanganiswa kwe-polymer kubandakanya indlela ebizwa nge-autocatalytic templating: njengoba i-polymer idelela amabhlokhi alandelayo ukuze ihlanganise amabhulokhi alandelayo ukuze ihlanganise ama-polymer okukodwa ukuze ihlanganise i-polymer kwisixazululo Dala ama-inch-onde ama-laminates angaphansi kwama-nanometers ama-4 aminyene.Lowo cishe owesilisa nowesigidi ephepheni lehhovisi elijwayelekile.
Ukuze unciphise izakhiwo zemishini yezinto ezisetshenziswayo ze-polymer, abacwaningi balinganisa amandla adingekayo ezimbozweni ezigciniwe nge-nylon enhle njenge-nylon eqinile njengensimbi eqinile njengensimbi ebukhali. Njengokuhlobanisa okuvikelayo ngezindawo zensimbi, ezinjengezihlungi zezimoto, noma njengesihlungi sokuhlanza amanzi.
Esikhathini esizayo, uStrano unethemba lokunweba indlela ye-polymerization kuma-polymers ahlukene ngaphezu kwale Kevlar Analog. "Ama-polmers asizungezile," kushona. " Cabanga nje uguqula izinhlobo eziningi zama-polymers, ngisho nalezo ezingaziwa ezingaqhuba ugesi noma ukukhanya, zibe ngamafilimu amancanyana angakwazi ukumboza indawo ehlukahlukene, "kusho ezinye izinhlobo zama-polymers manje," kusho ezinye izinhlobo zama-polymers.
Emhlabeni ozungezwe amapulasitiki, umphakathi unesizathu sokuthi ujabule ngelinye i-polymer entsha yalona izakhiwo zemishini kukhona noma yini okujwayelekile, okusho ukuthi kungenzeka ukuthi singakwazi ukufaka indawo yokuhlala nsuku zonke, kusuka ku-super-gront 2d polymer kuyisinyathelo esisezingeni elifanele ukukhulula umhlaba kusuka epulasitiki.
